Sale list
Tax Sale Auction List
When it runs
The fourth Monday in August each year at 10:00 a.m., in the first floor center hallway of the Barton County Courthouse in Lamar. The collector's bidder page sets the 2026 sale for Monday, August 24, 2026 at 10:00 a.m. and tells registered bidders to arrive by 9:45 a.m.
Registration and deposit

Register through the collector's online bidder form, print the confirmation, and return it to the Collector's Office by 4:30 p.m. on the Friday before the sale. No bidder is registered after that deadline. Bidders must be Missouri residents and must bring Missouri state issued identification on sale day. Anyone bidding for a company, corporation, lender or other organization must present documentation authorizing them to act on its behalf. Nonresidents of Missouri may not bid directly and must appoint a Barton County citizen as agent, approved by the collector by 9:30 a.m. on sale day, with the certificate of purchase issued to that agent. Every bidder also signs an affidavit stating they are not currently delinquent on any other property tax, and that affidavit must be completed at the Collector's Office no later than 9:30 a.m. on the day of the sale.

Sale format and venue
Bidding opens at the delinquent taxes, penalties and sale costs, and buyers must be present to bid. The winning bidder pays the full bid plus tax sale costs and recorder's fees immediately at the close of the sale, and the collector accepts cashier's check, bank draft, cash, credit or debit cards, and personal checks approved in advance. A bidder who fails to pay owes a penalty and the parcel is offered again. The collector issues a Certificate of Purchase after the sale, which the buyer holds through the one year redemption period or until the parcel is redeemed. Parcels are advertised in the Lamar Democrat for three consecutive weeks with the last insertion at least fifteen days before the fourth Monday in August, and printed lists are available at the Collector's Office from August 1.

Next sale
Tax sale scheduled for August 24, 2026.
When it runs
There is no separate deed auction. Deeds come out of the same fourth Monday in August sale once a parcel has moved past the third offering, and a buyer at a post third offering sale takes an immediate collector's deed with no redemption period.
Sale format and venue
A first or second offering buyer holds a certificate through the one year redemption period, obtains a title search dated no more than 120 days before applying for the deed, serves the ninety day notice of the right to redeem on the owner and every recorded claimant by both first class and certified mail, files the affidavit of notice with the collector, pays all taxes due, and surrenders the certificate to receive the collector's deed. A third offering buyer must send that notice within 45 days of the sale, which puts the earliest deed 135 days after the sale date. The collector warns that a deed not executed and recorded within two years of the certificate date costs the purchaser the lien, and that letting taxes on the parcel go delinquent forfeits it as well.

Barton County tax sale list and auction calendar

For Barton County tax sale 2026 searches, use the county-run sources below rather than a copied parcel list, and confirm the parcel, registration cutoff, deposit, and payment deadline against the county before you bid.

  1. Get the advertised list

    Use Tax Sale Auction List for the current advertised parcels, then recheck it before the auction.
  2. Register to bid

    Ask the county office how and when to register; many counties close registration days or weeks before the sale.
  3. Sale day

    Tax sale scheduled for August 24, 2026. The sale is live and in person; there is no online bidding platform. Confirm the venue and hour with the county office before you go.
  4. Confirm with the office

    If the list, platform, and notice disagree, use Barton County Collector-Treasurer as the source to confirm which parcels are actually offered.

Before you bid in Barton County

  1. Start with the live sale list

    Pull the current advertised parcels from Tax Sale Auction List. Lists can change before the sale, so recheck the county source before you price a parcel.
  2. Confirm registration and deposit

    Register through the collector's online bidder form, print the confirmation, and return it to the Collector's Office by 4:30 p.m. on the Friday before the sale. No bidder is registered after that deadline. Bidders must be Missouri residents and must bring Missouri state issued identification on sale day. Anyone bidding for a company, corporation, lender or other organization must present documentation authorizing them to act on its behalf. Nonresidents of Missouri may not bid directly and must appoint a Barton County citizen as agent, approved by the collector by 9:30 a.m. on sale day, with the certificate of purchase issued to that agent. Every bidder also signs an affidavit stating they are not currently delinquent on any other property tax, and that affidavit must be completed at the Collector's Office no later than 9:30 a.m. on the day of the sale.

  3. Check the state rules that change the bid

    Read the Missouri due-diligence checklist before bidding. Redemption, liens that survive a tax deed, title cleanup, and payment deadlines can change what a parcel is worth.
  4. Set a walk-away number

    Work out what the parcel is actually worth with the rural land value estimator, then turn it into a ceiling with the tax deed max-bid calculator.

Over-the-counter (leftover) purchases

Missouri publishes no standing over the counter certificate list. The equivalent route is the post third offering sale. Parcels that draw no buyer at a third offering must be advertised or offered again once every 30 days, and where the county's appointed trustee declines to take a parcel the collector may sell it at any time and for any amount. A buyer at any of these sales gets an immediate collector's deed, no redemption period, and must first pay every tax that fell due after the taxes named in the advertisement. Parcels the trustee did take are held for the taxing funds and sold on order of the county commission. Ask the collector for the current post third offering list and its bidding terms, because the format varies by county.

County notes

  • The sale runs live at the Barton County Courthouse in Lamar and buyers must be present to bid, so there is no remote bidding for this county.
  • Registration closes at 4:30 p.m. on the Friday before the sale and the affidavit of no delinquent taxes must be signed by 9:30 a.m. on sale day, so arriving only on Monday morning is too late to bid.
  • Payment is due immediately at the close of the sale in cleared funds, and the collector states that all sales are final with no refunds, so research each parcel and locate it on the ground before bidding.
  • Delinquent taxes can be paid to the collector at any time before the sale date, so parcels drop off the auction list right up to sale day. Re-check the list on the morning of the sale.
  • Bidding on a first or second offering parcel buys a lien, not the property. Other liens are not wiped out at the sale or during redemption, and the owner or occupant may stay in possession through the redemption year.

Missouri rules

Max interest rate
10% per year, set by statute (bidding is on price)
Minimum return
No statutory minimum return; what you earn is set by the price at the sale
Redemption
After a first or second offering sale, the owner and other interested parties hold an absolute right to redeem for one year, then a defeasible right that lasts until the purchaser actually acquires the deed. A purchaser must serve the 90 day notice of the right to redeem before the date on which the deed can be acquired, so the practical window usually runs past the one year mark. After a third offering sale, redemption runs 90 days, and the purchaser must give notice to recorded claimants within 45 days of the sale. After a post third offering sale, there is no redemption period and the deed issues immediately. Minors and incapacitated or disabled persons have a longer right, running five years from the last payment of taxes by that person or a predecessor. The right also ends if the certificate lapses because the purchaser failed to record the deed within 18 months.
Deed deposit
The winning bidder must pay the full amount of the bid to the collector immediately at the sale. Chapter 140 sets no advance bidder deposit and no balance due window. A bidder who fails to pay forfeits a penalty of 25 percent of the bid to the county school fund and the parcel is offered again at once as though no sale had been made. Counties running an online or registered sale may impose their own deposit and registration terms on top of the statute, so confirm them with the collector.
Surplus proceeds
Any amount above the taxes and costs is surplus. The collector pays it into the county treasury, where the treasurer holds it in trust for the lesser of three years or 90 days after the redemption period expires. It is distributed first to the former lienholders of record in the priority their liens held on the date of the sale, then to the former owner. No distribution other than through the redemption process may occur until 90 days after the redemption period ends, and a claimant must file a written claim with the county commission within those 90 days, referencing the recorded lien it rests on. The county pays no interest on the fund. Anything still unclaimed at three years becomes the permanent school fund of the county.
Governing statute
Mo. Rev. Stat. Chapter 140

A tax deed does not convey marketable title. Most buyers file a quiet title action before they can resell or insure the property. See the due diligence guide.
